A few people have asked me about the H250 adaptor box that I built to use on my FT-857 manpack. It allows the operator to switch between using the standard Yaesu fist microphone or an Ex MOD H250 handset.

I don’t have any build notes but here are a few images that may help anyone who wants to build one.
